Abstract

L'invention concerne une machine à emballer et un appareil de pesage de coûts et d'encombrements réduits et permettant de diminuer le temps nécessaire entre la fabrication d'éléments emballés et leur pesage, d'où un gain de productivité. Les ensembles d'éléments emballés sont pesés par une cellule de charge située dans le boîtier de la machine à emballer. Les ensembles d'éléments emballés ne devant pas être acheminés par transporteur à courroie vers un poste de pesage séparé de la machine à emballer, les coûts d'équipements sont réduits, ainsi que l'espace nécessaire pour les ensembles d'éléments emballés y compris les équipements périphériques. En outre, la productivité est accrue, étant donné que le temps requis aux ensembles d'éléments emballés pour satisfaire à une exigence de pesage et former des produits est réduit.
